Finite Element Strength Analysis and Optimization of Cutting Tools Based on Fluid-Structure Interaction

Abstract In this paper, taking a cutting tool as an example and aiming at the problem of stress fatigue evaluation optimization, finite element model including tool, shaft, washer was established by using methods simulation testing, strain analysis in working process completed. A single fluid-structure coupling method applied to calculate dynamic load high-speed food cutting, ABAQUS used analyze under load. Practical engineering applications showed that practical feasible, calculation results were consistent with actual measurements. The analytical can accurately reflect real conditions key parts be quantitatively assessed, providing reference for optimal design tool.
